2 Claims.

This invention relates to nozzles yand has for one of its objects theprovision of a nozzle that includes several passageways therein and avalv-e for controlling the ilow of liquid through said passageways asdesired, including a blow-oil type of strainer in one of saidpassageways and which latter passageway communicates with a spray portor tip.

Another invention is the provision of a nozzle provided with a valvethat is easy to turn regardless of the water pressure against the same,and easy to service and recondition.

A still further object of the invention is a nozzle provided with aone-piece rotary valve body that provides an efficient control for aliquid free from undesirable leakage and which valve is easier to turnthan heretofore in valves of the same general type of one-piece plugvalves.

In the drawings,

Fig. l is an elevational view of the nozzle showing a spray tip and astraight nozzle tip on the ends of the discharge openings.

Fig. 2 is a sectional view through the nozzle of Fig. 1 but with thetips omitted.

Fig. 3 is a part elevational, part sectional view of the nozzle taken atright angles to the view in Fig. 2.

Fig. 4 is a sectional view through a modified form of nozzle showing amodified valve plug and valve structure.

In detail, referring to Figs. 1 to 3, the nozzle comprises a housinggeneral-1y designated I, provided with an inlet 2 opening outwardly ofone side of the housing, anda pair of discharge passageways 3, 4 openingoutwardly of the side of the housing that is generally opposite theinlet. Within the said housing is an enlarged chamber 5 in which isrotatably supported a valve body `6, which valve body is provided with athrough port 'I and a port `8 at right angles to port 'I andcommunicating with the latter at a point centrally between its ends.

The outlet passageway'S is preferably in axial alignment with the inletpassageway 2, and said inlet and outlet passageways open into chamber 5at diametrically opposite points in the cylindrical walls 9 of saidchamber, the remaining walls I0, II being at and in opposed relation toeach other.

`The -body 6 comprises the central segment of a ball having flattenedparallel opposite sides adjacent walls ID, II respectively, and acircular periphery that conforms to spherical contour in cross section,as best seen in Fig. 3.

Coaxial trunnions I2, I3 project from opposite 2 sides of said body lIcoaxial with the latter, the trunnion I2 being rotatably supported in a,recess I4 in wall I0, there being a yieldable rubber or composition diskI5 between the base of said recess and the end of trunnion I2.

The trunnion I3 extends through a central opening in wall I l andthrough a stuffing box I5 tothe outside of the housing where it isprovided with a wing member or handle I1 for turning by the fingers ofthe hand.

The flat Wall II comprises a disk that is threadly secured in an openingin the side of the housing, which opening is larger than the diameter ofthe body IIi. Thus upon unscrewing the disk II, and loosening a pair ofcoaxial sleeves at opposite sides of said body 6, as will later be exnplained, the valve body yIi may be freely withdrawn from chamber 5Without removing the handle Il or uns-crewing the stuiilng box.

An -annular thrust gasket or :collar I8 of yieldable material, such rasrubber or the like, is around the trunnion I3 between disk II vand theplug body `6. While the end of trunnion I3 that extends through theIdisk II and stuffing box I6 is slightly smaller in vdiameter than theportion of the trunnion adjacent the body E and that is within collarI8,.nevertheless the body lli is yieldably held centered in the chamber`5 between walls Ill, II by said collar I8 andthe disk I5.

The spherical peripheral surface of the body -ii is spaced from thecylindrical walls 9 of chamber 5 by sleeves 20, 2| respectivelyreciprocable in thc inlet passageway 2 and in the outlet passageway 3.These sleeves and the ports l, 8 `are all prefu erably of the samediameter.

Sleeves 20, 2| project into chamber 5 and their projecting ends are of acontour conforming to the spherical surface of the periphery of the bodyE and said ends are yieldably held in frictional engagement with saidspherical surface by means of collars 23, 24 respectively, positionedbetween the opposite ends of sleeves 20, ZI and retainer rings 25, Z6that are respectively threaded in the inlet :and outlet passagewaysadjacent enlarged interiorly threaded ends 21, 28 of said passage* ways.

The collars 23, Z4 and rings 25, 26 are of the same internal diameter asthe diameters `of sleeves 2i), 2 I. Rings 25, 2B are adapted to berotated by a, spanner or screw driver .and by adjusting said ringsrelative to each other, the body 6 is substantially `suspended betweenthem so that there is little friction between the trunnions and theirbearings. By retracting rings 25, 25 the sleeves 2|, 20 will be loosenedrelative to body `li a suf- 3 cient degree to 'permit free withdrawal ofthe body from the chamber 5 after disk Il is removed.

From the foregoing description it will'be seen that there is a spacebetween the body I6 and the walls of chamber 5 in which water Ipressuremay be around body 5, but when the valve body is in closed position thewater pressure in the inlet will tend to .urge-the body against theprojecting end of sleeve 2|. The frictional engagement between sleeve 2|and the body is practically all the resistance there is, although thetrunnions may offer a little. However, the valve body may be rotatedalmost effortlessly by two rlngers of the hand even though the water.pressure against the body is say, 300 lbs. per square inch'or more.

The spherical contour of the periphery of the body 6 and thecorresponding contour of the projecting ends of the sleeves -enablesthem to be quickly and easily reground in the field should yleaksdevelop due to scoring of the lbody or sleeve ends from sand or, otherabrasive.

A straight nozzle tip 30 or other nozzle `tip of any desiredconformation may be quickly screwed into the threaded end 28 of thehousing. Ordinarily this discharge passageway is for a. solid stream.

The discharge passageway 4 preferably opens outwardly of housing in thesame direction as the discharge passageway 3,.but it opens into thechamber l5 through cylindrical wall 3 at a point midwaybetween sleeves2|), 2|. l

The side of housing I is formed with an enlargement 3| through whichsaid passageway 4 extends and said passageway is enlarged at 32 adjacentthe point where it opens into cham- .ber 5.

Extending across said enlarged portion 32 in a direction at .rightangles to the axis of sleeves 2|), v2| is a tubular screen 33 that i-spreferably of perforated metal. One end of said screen is secured inpassageway4 adjacent the point where .it opens into chamber5, while theother end is secured in a bore 34 that is coaxial with the screen I andwhichbore opens outwardly .of the enlarged lplug -a .predetermineddistance the port 36 is uncovered whereby any Water entering the screenatits end opposite plug 35 will pass through the screen and out of port36 thus cleaning the screen of any debris, etc.

Discharge passageway 4 continues from the enlargement 32 in graduallydecreasing diameter, and angularly relative to the axis of the screen 33through an exteriorly threaded projection 36' that extends in the samedirection as the discharge end 28 of the main body, and substantiallyalongside said end 28. A spray or fog nozzle tip 3S is adapted to bescrewed onto projection 36, or any other desired nozzle tip may bescrewed onto said projection.

All water or liquid passing to the spray nozzle 33 must pass through thescreen 33, therefore the spray nozzle will not be clogged by debris andrendered useless at a critical time. If the screen should becomeclogged, it can be quickly cleaned by merely partially unscrewing the.plug 35.

The port `8 in the body 6 functions to deliver `water or liquid to thedischarge passageway 4 when the body 6 is turned to close passageway 3and to place port 8 in registration with the inlet sleeve 20. When thebody is turned to the position seen in Fig. 2, both discharge ports areclosed, and by rotating the body 6 clockwise (as seen in Fig. 2) theport 'l is aligned with sleeves 23, 2| while passageway 4 is closed.

In the form illustrated in Fig. 4, the housing 40 substantiallyresemblesthe. body but the does not have a sleeve.

screen 33 and plug 35=are omitted, also the discharge passageway 3(indicated at 4| in Fig. 4) Instead of such sleeve, the body 42 (similarto body 6) is formed with a bore 43 in axial alignment with the port 44(corresponding vtofpo-rt 8). The bore 43 is interiorilyfthreaded for amember 45. A plug 46 projects from the bore 43 and is formed with acurvedouter surface that is adapted to slidably engagethe cylindricalsurface of chamber 5. A yieldable disk 41 .of rubber or the like, isinterposed between member 45 and plug 46 so as to hold the voutersurface of the `plug in yieldable engagement 'with said *cylindricalsurface of chamber 5.

Exceptfor theA above, the structure is the same as in Figs, 1 "to-Bandthe same numbers are used to designate -correspondingparts The pressureof 'plug 4l 'on thewalls of chamber 5 is adjusted by rotation of themember 43 until the body "42 is .practicallysuspended between saidVplugand"s1eevef-2l). While the plug 47 does not `always remain at apoint diametrically across chamber 5'from the sleeve 20, nevertheless itfunctions to relieve' the friction between the trunnions and the housinglsufficiently to 4make an easy 'operating valve.

It is 'tobe..understood that the detailed descripti-on and 'drawingsare` not to be considered restrictive ofthe invention, but merelyillustrative thereof.
